Hello! I'm a full-stack developer based in Bolivia!

Full-Stack Developer ( Frontend / Backend / Mobile )
About me
Who am I?
I'm Olivio, a full-stack developer from Tarija, Bolivia. What I enjoy most is taking a loose idea and turning it into something people actually end up using — from the very first screen all the way down to the backend that holds it up.
I work with React, Node.js and React Native, but more than the tools I care about solving the real problem underneath: code that's easy to follow, interfaces that feel comfortable, and systems that hold up as they grow. I'm always chasing the next challenge to keep getting better.
